Hi all,

Just got a runner 3 + cardio watch last week and using the firmware version of 1.7.64.

When I set the Heart Rate sensor to "on", I can see the green light on the back of the watch flashing and the bpm reading initially is showing --.

But after about 10 seconds it will start displaying some bpm settings (something like 65 or sometimes higher) even though i have not put the watch around my wrist at all.

Is this a normal behaviour or am i having a faulty unit?

Thanks all for answering.
